* fix(cli): use normalizeErrorMessage so validate/inspect never print "[object Object]" The validate and inspect (layout) commands formatted thrown values with `err instanceof Error ? err.message : String(err)`. When a browser/CDP/ Puppeteer protocol error or a structured page error reaches the formatter as a plain object without a string `message`, `String(obj)` yields the useless literal "[object Object]", hiding the real cause. Route those paths through the existing shared `normalizeErrorMessage` helper, which returns an Error's message, a string as-is, an object's `.message` when present, or a compact JSON serialization otherwise (with a key-list and String fallback for circular/opaque objects). Also fold the duplicated local `errorMessage` helpers in batchRender and preview into the same shared helper. Covered by added assertions in errorMessage.test.ts for the no-message object and Puppeteer-style protocol-error object cases. * fix(cli): route remaining browser/process error sites through normalizeErrorMessage The validate/inspect fix routed only those two commands through the shared normalizeErrorMessage helper. The same err instanceof Error ? err.message : String(err) pattern survived in the other commands that drive a headless browser or an external process (ffmpeg, Docker, CDP) or surface a network API error, so a thrown structured object without a string message would still render as the useless literal [object Object]. Route those sites through the shared helper: snapshot.ts (the closest sibling to validate/inspect, same bug class), render.ts (Chrome launch + Docker build), capture/index.ts and commands/capture.ts (page-driven extraction), auth/browser.ts, browser/manager.ts (Puppeteer browser resolution), and the cloud/lambda paths (cloud/render.ts, cloudrun.ts, lambda/render-batch.ts, lambda/policies.ts, cloud/detectAspectRatio.ts) that surface API/network error objects. Only the message-deriving expression changes; control flow and error propagation are untouched. capture/index.ts keeps appending the stack for real Errors and only routes the non-Error branch. Adds a helper test for a structured CDP-style error object (code + nested data, no message).
hyperframes
CLI for creating, previewing, and rendering HTML video compositions.
Install
npm install -g hyperframes
Or use directly with npx:
npx hyperframes <command>
Requirements: Node.js >= 22, FFmpeg
Commands
init
Scaffold a new Hyperframes project from a template:
npx hyperframes init my-video
cd my-video
preview
Start the live preview studio in your browser:
npx hyperframes preview
# Studio running at http://localhost:3002
npx hyperframes preview --port 4567
render
Render a composition to MP4:
npx hyperframes render ./my-composition.html -o output.mp4
lint
Validate your Hyperframes HTML:
npx hyperframes lint ./my-composition
npx hyperframes lint ./my-composition --json # JSON output for CI/tooling
npx hyperframes lint ./my-composition --verbose # Include info-level findings
By default only errors and warnings are shown. Use --verbose to also display informational findings (e.g., external script dependency notices). Use --json for machine-readable output with errorCount, warningCount, infoCount, and a findings array.
compositions
List compositions found in the current project:
npx hyperframes compositions
benchmark
Run rendering benchmarks:
npx hyperframes benchmark ./my-composition.html
doctor
Check your environment for required dependencies (Chrome, FFmpeg, Node.js):
npx hyperframes doctor
browser
Manage the bundled Chrome/Chromium installation:
npx hyperframes browser
info
Print version and environment info:
npx hyperframes info
